@Jaganlon, I too am in the same situation from yesterday, I doubt that WES is using COE's mail id from the website. This mailbox is full and mails are actually not getting delivered.
What to do if this is the case?
Allow University guys to take two to four weeks to respond. There are lot of chances they might have seen your email too. You cannot expect the University send next day. Give atleast a minimum span of 2 to 3 weeks.
